PABTS FOR OPHTHALMIC MOUNTINGS.

Applicationfiled February 23, 1922. Serial No. 538,685.

1 '0 alt whom it may concern Be it known that we, ELMER L. SCHU- MACHER and WILLIAM H. BOUTELLE, citizens of the United States, residing at Southbridge 5 and Sturbridge, respectively, in the county of Worcester and State of Massachusetts,

have invented certain new and useful Improvements in Parts for Ophthalmic Mountings, of which the following is a specification.

This invention relates-to improvementsin parts for. ophthalmic mount1ngs,and has particular reference to combination mountings formed from a combination of metallic and non-metallic parts.

One of the principal objects of the present invention is the provision of a novel and improved structure of this type in which it is possible to make up temples, separable rims,

9 or other similar parts, from sheet stock of mottled 01' other form, as desired, in place of using rod or tubular stock, as has hitherto been deemed necessary.

A'further object of the present invention is the provision of a novel and improved construction through the use of which it will be possible to form temples or other parts for ophthalmic mountings having a metal core enclosed by non-metallic material in which said non-metallic covering for the temple may be formed from the same stock as the front or lens receiving portion of the mounting, so that the parts will exactly match in color, marking, and the like.

A further object of the invention is the provision of a novel process of producing parts of this character and of a novel and improved completed construction which will better retain its shape and stand up I more satisfactorily under service conditions than structures hitherto known.

Other objects and advantages of the improved construction should be readily apparent by reference to the following description taken in connection with the accompanying drawings, and it will be understood that any modifications in the specific details of construction shown and described may be made within the scope of the appended claims without departing from or exceeding the spirit of the invention.

Figure I is a rear view of a mounting embodymg the improvements.

'ther step in thetconstruction of this form of mounting. I

Figure IX is a view of a modified manner of constructing the article in question.

Figures X, XI and XII are sectional views illustrating a further modified manner of producing the desired structure.

In the drawings, in which similar characters of reference are employed to denote corresponding parts throughout the several views, the numeral 1 designates the bridge of a mounting provided with the lens receiving frames 2 integral therewith, the whole being stamped or cut from a sheet of suitable composition material, which may be either of plain color or mottled in imitation of tortoise shell or other similar substances. Carried by said front are our improved temples. In that form of the invention illustrated in Figures I to V inclusive, the temples have been formed by using a flat sheet of material 3, forming therein the longitudinal cuts 4, separating the same into strips substantially square in cross section, and splitting each of these strips as at 5 to form the two parts designated as A and B. The parts A and B, as shown in Figures II and III, are then milled as at 6 to produce a longitudinally extending groove for the major portion of the length of the strip, the groove terminating short of one end of the' strip in the drilled out hole or enlargement 7, this enlargement being of size to receive a ball or enlargement 8 on the end of the metal temple member 9 which is adapted to be inserted and fit within the groove 6, and is provided with a butt or joint portion 10 to project exteriorly of the temple, as is shown 105 in Figure V.

The two parts A and B having been suitably prepared the metal temple 9 is inserted within the groove and ball receiving socket and the two parts are then firmly pressed together with an intervening coating of cement, as at 11. By referring to cement is meant that theproduction of adhesion between the joined surfaces, this being produced either by application of a coating of in holding the joint together, if desired, the

metal member 9 maybe made with projecting prongs 12, which bite into the material of the sections A and B and if desired may so project therefrom that their heads in the finalarticle may be swaged as at 13, Figure V. In any event, the parts having been joined, the block comprising the composition covering and metallic insert may then be milled, turned, swaged, or otherwise formed into the shape of the final temple, as shown in Figure V, after which operations the joint at 11 will be entirely invisible and the article will present the appearance and have the durability of a unitary structure of all composition, together with the added desirability of the metallic insert, and being formed from the same sheet material as the front in the case of all zylonite frames, can be made to exactly match the front or can be produced with mottled or other desired results impossible where extruded rod type or other stock is employed.

Figures VII and VIII illustrate another method of accomplishing the same result, in which in place of cutting straight strips from the sheet of material, the temples are blocked out in their. final shape and then split, the other operations tion in which the metal receiving groove 14 is milled into the sheet of stock and the groove subsequently closed by a cap or cover V member 15.

Figures X, XI and XII illustrate a form in which the stock is slotted from one corner, as at 16, the hole being then opened up to facilitate insertion of the wire 9 and subsequently the joint closed, as shown in Figure XII, and the completed temple pro duced from the block in question. 1 Whatis claimed is:

1. A temple for an ophthalmic mounting, comprising a composition body consisting of two sections having their adjacent faces provided with registering grooves, a metal temple core received in said grooves, means for anchoring said core therein, and means for securing together the two sections.

2. A temple for an ophthalmic mounting, comprising 'a composition body consisting of two sections having their adjacent faces provided with registering grooves, a metal temple core received in said grooves with one end projecting beyond one end of said body for connection with the mountingg'the other end terminating short of the other end of said body and provided with an enlargement countersunk in the corresponding ends of said grooves for anchoring said temple core in said body, and means for securing together the two sections.

3. A temple of the character described comprising nonmetallic members grooved on one surface, said grooved surfaces being joined together, and a metallic core em-' bedded in the grooves and having a hinge buttextending beyond the end of the nonmetallic members.

In testimony whereof we have afliired our signatures.
